Barnesiella ssp. is a small group of two species of bacteria that are usually only found at reasonably low levels in the gut. Generally Barnesiella makes up less than one percent of an individual’s total gut bacteria. Some experiments have shown that the deliberate introduction of Barnesiella into the gastrointestinal tract may prevent the spread of highly antibiotic-resistant bacteria.

Barnesiella is named after the British microbiologist Ella M. Barnes, who contributed much to knowledge of intestinal bacteriology and to anaerobic bacteriology in general.

What does it mean if your Barnesiella spp. result is too high?

- Barnesiella spp. can be elevated due to aspirin use.

- Higher fecal Barnesiella have been associated with protection against Vancomycin Resistan enteroccus (VRE) in transplant patients.

- It has also been associated with a negative influence on Clostridium difficile infection.

- Antibiotics have been shown to have negative impact on the abundance of Barnesiella spp. in the gut.

- Lactobacillus kefiri was given to 20 healthy volunteers for one month and after the probiotic was discontinued for a month, Bacteroides, Barnesiella, Clostridium, Veillonellaand other species were significantly reduced compared to baseline samples. [L]
